Atomic Coherence of 2 Minutes and Instability of $1.5×{10}^{−18}$ at 1 s in a Wannier-Stark Lattice

Atomic Coherence of 2 Minutes and Instability of $1.5×{10}^{−18}$ at 1 s in a Wannier-Stark Lattice Clock

Author(s): Kyungtae Kim, Alexander Aeppli, William Warfield, Anjun Chu, Ana Maria Rey, and Jun Ye We explore the limits of atomic coherence and measurement precision in a $^{87}\mathrm{Sr}$ optical lattice clock. We perform a detailed characterization of key effects, including lattice Raman scattering and atomic collisions in a shallow lattice configuration, determining a 174(28) s $^{3}{P}_{0}$… [Phys. Rev.
